Write a formula for finding the volume of a cube. use an exponent and the variable represent the side lengths. then use the formula to find the volume of a cube with side lengths of 7 inches.

All the sides of a CUBE are equal..
Therefore, we can conclude that the formula for the volume of a cube is:
                                          =side³=s³
                             Or         =Base area×height
 Which is the same thing, because we multiply the same numbers thrice.
 V of cube=side³
                =7³               (side length is 7 in)
                =343 in³
